Scott….one more thing vis a vis China….
I know you are probably prescription drug averse so I suppose Ambien for jetlag is a non-starter suggesion. That said, for a long time I used Melatonin for jetlag per my family physician’s rec. It’s non-prescription, non-narcotic, non-habit forming, and sold in the vitamin supplement sextions of the supermarket or drug store. I used to take the 3 mg pills. I was told a secret to put it under my tongue and let it dissolve there. It was quite effective. Look it up and take a bottle along. You won’t regret it.
Have fun over there!
